AUTOMATIC COMBINATION SFARK AND CARIB'URE TOR CONTROL.

Application filed September 30, 1925. Serial No. 59,693.

This invention relates to an automatic combination spark and carburetor control, and the obj-ectofvmy. invention is to place the controlv of the gasoline supply through the carburetor, where it will be automati-1 cally and perfectly regulated according to the requirementsat all times.

With the foregoing and other objects in view, my invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a view in side elevation of a gasoline motor, showing my device applied thereto, while Figure 2 is a front view of the same.

Figure 3 is an enlarged perspective view of the device.

Figure 4 is a perspective view of another embodiment of my invention.

- Figure 5 is a View in elevation of a part of the embodiment shown in Flgure 4, while Figure 6 is a view looking at the disclosure in Figure 5 at right angles thereto.

Referring to the drawings by numerals,1 designates the carburetor of a motor; 2 is the spark control rod, and 2 is the gasoline control rod.

In carrying out my invention, I fasten an arm 3 to the spark control rod 2, which arm 3 is provided in its outer end with an apertur-e through which the angular end 4 of connecting link 5 extends. The opposite end 6 of link 5 is bent at right angles and extends through the eye 7 of the horizontal end 8 of the vertical primary rod 9. I

The rod 9 extends through sleeve 10 of plate 11, which plate 11 is fastened to the motor as shown in Figure 1. The lower end of rod 9 is fastened in sleeve 12, and the upper end of auxiliary rod 13 is detachably fastened in the lower end of sleeve 12 by the screw 14. Formed on the lower end of rod through the carburetor can be increased or decreased, as the operator desires. By means of screw 14, the carburetorcan be adjusted according to requirements.

In the embodiment shown in Figures 4 :to

6, the connccting link 5 is provided with. an

angular end 4, like-link 5, but at .oneend 20, theend: is formedsimilarto end 4.. This end 20 extends throughplate 21, which plate 1s secured by a screw 22'to the frame 23.

This frame 23 has an inverted U-shaped body and the ends 24 of frame 23 extend outward, through which pass L-shaped bolts 25. These bolts 25 clamp over the ends 17 of portion 18, thereby locking the frame 23 upon the stem of the valve of the carburetor, 7

ing the amount of gasoline being supplied to the carburetor.

In operation, the operator fastens the primary rod 9 and the auxiliary rod 13 in their assembled position by means of the sleeve 12 and the butterfly bolt 14, having determined by experimenting the exact adjustment of these rods, one with respect to the other, and then by operating the spark control rod 2, the arm 3 will be swung in the direction indicated by the arrow A (Fig. 3) and as a result, the connecting link 5 will be moved either forward or backward as indicated by arrow B, whereupon the portion 8 of rod 9 will be swung in a horizontal plane as indicated by arrow C, which will result in turning the valve stem 19, either for allowing more gasoline to be supplied to the motor, or decreasing the amount of gasoline, depending upon the rotary movement imparted to the spark control rod 2, which is controlled by the operator at or near the steering wheel carried by the steering post 26.

It will be understood that my invention combines the gas and spark service in such a positive way that in advancing or retarding the spark on the hand lever on the steering post, the operator will positively and of necessity increase or decrease the supply of gasoline. When the spark is retarded the carburetor will be opened for a richer mixture, and when the spark is advanced it gives a leaner mixture which is absolutely necessary for proper combustion which is automatically and positively produced instantly through the necessity of advancing the spark.

While I have described the preferred embodiments of my invention, and have illustrated the same in the accompanying draw ings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same, and I, therefore, reserve the right to make such alterations or changes as shall fairly fall Within the scope of the appended claim.

WVhat I claim is:

In a device of the class described, the combination with a spark control rod, of an arm secured to said spark control rod, a connecting link, one end of said link connected to said arm, a primary vertical rod provided With a horizontal upper end, said upper end terminating in an eye, one end of said angular link extending through said eye, a sleeve having the lower end of said rod extending thereinto, an auxiliary rod extending at its upper end into said sleeve, a screw or bolt in said sleeve and fastening said auxiliary rod therein, said auxiliary rod terminating at its lower end in an inverted U-shaped frame, said U-shaped frame provided With bifurcations in its ends, and a T-shaped valve controlling stem movably mounted in said bifurcated ends of the U-shaped frame.

In testimony whereof I hereunto aiiix my signature.
